Operational Notes

Medium Wide - Deep Field. Entry level Science Platform.  Typically used for Science Missions and Photometry. FITS and TIF file formats. Raw data can be found at data.itelescope.net.

• Dark Frame calibration data is available for  60, 120, 180, 300, 600  second exposures. Binx1 - Binx2. Non Anti Bloom Gate (NABG) CCD. Bright stars will bloom or bleed in long exposures.  Recommended Maximum Exposure 600 seconds.
• T5 is one of the busiest remote telescopes on the iTelescope Network. It allows its many drivers to gather valuable science data with its moderate wide angle FoV and sharp Takahashi optics. Coupled with its ST10XME CCD NABG camera, T5 can go very deep and wide with ease and very high reliability. But care should be taken by those new to NABG cameras.
• Keep your exposures short if very bright stars are in your target FoV. Trial and error can help you fine tune exposure times as well and the right processing tools to repair the image and remove blooming if necessary.
• IMPORTANT NOTES: Sub-exposure times are limited to 300 seconds or less.
